What is Q235B steel?
Q235B steel plate represents the epitome of low carbon steel technology, being elegantly defined within the national standard GB/T 700-2006 'Carbon Structural Steel'. This ubiquitous material stands as a cornerstone in China's steel industry, known for its affordability and versatility. Its broad applicability makes it an ideal choice for products and projects where high performance isn't a stringent requirement, offering a perfect balance of quality and cost-effectiveness.
The difference between Q235A and Q235B.
The distinction between Q235A and Q235B carbon steels lies in the carbon content as defined by the national standard GB700-88. Q235A is characterized by a carbon content ranging from 0.14% to 0.22%, making it distinctly different from Q235B. This subtle variation in composition can significantly influence the material properties and suitability for various applications.
Typically, steel mills ensure clear identification by marking the finished profiles on the identification plates before dispatching. Users can easily ascertain whether the material is Q235A, Q235B, or any other type by examining these plates. The specified design pressure stands at P≤1.6MPa, with an operational temperature range of 0~350ºC, and a steel plate thickness starting from >=20mm, ensuring robustness and reliability in demanding environments.
The Application of Q235B Steel
Q235B steel grade is an integral part of modern civil engineering applications. Its use spans a multitude of structural solutions, from industrial and residential buildings to essential components in power transmission towers. This steel is foundational in crafting elements of equipment, offshore structures, oil and gas platforms, automobile bridges, and a myriad of other architectural and infrastructural ventures, showcasing its indispensable role in both traditional and innovative construction.
